Book Description
The primary purpose of this research is to provide an estimate of Chinook salmon abundance entering the Kenai River that is independent of existing sonar programs. These estimates of abundance will be used, in conjunction with sonar based estimates of abundance to develop escapement goals for Kenai River Chinook salmon. A secondary purpose of this research is to monitor Chinook salmon migration within the Kenai River drainage for the purpose of informing management decisions with respect to time and area.

Book Description
The migratory timing and distribution of Kenai River Chinook salmon was examined using radio telemetry for 2014 and 2015. Spawning destinations were determined for 153 Chinook salmon in 2014 and 39 in 2015. Radiotagging data since 2010 are presented with data from 2014 and 2015 when appropriate. Of the Chinook salmon radiotagged during the early run in 2014, 81% (SE 4%) spawned in tributaries (range 72-85% since 2010). Radiotagged tributary-spawning Chinook salmon primarily spawned in the Killey River, Benjamin Creek, and Funny River during all years. Estimated Killey River Chinook salmon escapements based on weir passage and radiotag distribution within the Killey River drainage ranged from 3,564 (SE 500) to 3,934 (SE 627) during 2012-2015. In 2014, all but 2 Chinook salmon radiotagged during the late run (after 30 June) spawned in the mainstem of the Kenai River. The highest proportion of radiotagged mainstem spawners in 2014 were downstream of the Soldotna Bridge at RM 21 (39% SE 6%) and between the Moose River confluence at river mile (RM) 36.3 and Skilak Lake outlet at RM 50 (36% SE 6%). During 2012-2014, an average of 4.0% (SE 1.2%) of assigned mainstem spawning destinations were downstream of the RM 13.7 Chinook salmon sonar. For tributary spawners during 2010-2014, 69% and 95% were in waters with existing closures and restrictions upstream of Slikok Creek on July 1 and July 15, respectively. On 1 July, 23% of tributary spawners were in waters open to fishing upstream of Slikok Creek and 8% were downstream of Slikok Creek. In July, mainstem-spawning Chinook salmon radiotagged in 2012-2014 were primarily (51-59%) in waters open to fishing downstream of Slikok Creek; the rest were upstream: 23-30% in unrestricted waters and 12-20% in closed or restricted waters.

Book Description
Report on estimates of total abundance (total run size), exploitation rate (maximum sustainable exploitation rate), and migration timing (lower and middle runs, Alaska and upper runs, Canadian origin) of chinook salmon (Oncorhynchus tschawytscha Walbaum) in the Yukon river, Alaska between 1982 and 1986.

Book Description
A stock-specific abundance and run timing model (SSART) was fit to relative and absolute estimates of abundance, genetic stock identification data, radiotelemetry data, and estimates of harvest for Kenai River Chinook salmon (Oncorhynchus tshawytscha) from 2007 to 2014. The methods follow a model of the 2007-2012 data except that inference is restricted to Chinook salmon 75 cm mid eye to tail fork (METF) or longer for all results in this report. Bayesian statistical methods were employed to estimate inriver abundance and run timing by stock at river mile 8.6 of the Kenai River. Abundance of early-run Chinook salmon ranged from 1,940 (SE 307) in 2013 to 8,637 (SE 2,215) in 2007. Abundance of late-run Chinook salmon ranged from 9,949 (SE 2,138) in 2010 to 37,180 (SE 10,340) in 2007. Fish from Killey River-Benjamin Creek, Funny River-Slikok Creek, and Quartz-Crescent creeks migrated upstream primarily prior to 30 June; fish from Grant Creek and Russian River migrated upstream primarily between 16 June and 31 July; and fish from Mainstem Kenai River-Juneau Creek migrated upstream primarily after 16 June. Tributary stocks had greater relative abundance within the run before 16 June and the Mainstem-Juneau Creek stock had greater relative abundance after 30 June. Between 16 June and 30 June, tributary stocks had greater relative abundance in 6 of 8 years while Mainstem-Juneau Creek fish had greater relative abundance in the other 2 years.

Book Description
A stock-specific abundance and run timing model (SSART) was fit to relative and absolute estimates of abundance, genetic stock identification data, radiotelemetry data, and creel survey estimates of harvest for Kenai River Chinook salmon (Oncorhynchus tshawytscha) from 2007 to 2012. Bayesian statistical methods were employed to estimate inriver abundance and run timing by stock at river mile 8.6 of the Kenai River. Abundance of early-run Chinook salmon ranged from 6,739 (SE 819) in 2012 to 12,300 (SE 2,087) in 2007. Abundance of late-run Chinook salmon ranged from 22,190 (SE 3,815) in 2010 to 48,370 (SE 8,641) in 2007. Tributary stocks had greater relative abundance within the run before 15 June and the Mainstem-Juneau Creek stock had greater relative abundance after 15 June. Fish from Killey River–Benjamin Creek, Funny River-Slikok Creek, and Quartz-Crescent creeks migrated upstream primarilyduring the first 3 of 6 time strata; fish from Grant Creek and Russian River migrated upstream primarily during the third through fifth time strata; and fish from Mainstem Kenai River-Juneau Creek migrated upstream primarily during the last 3 time strata.
